Hi,
I have two groups of data of different size:
group A: x1, x2, , x_n;
group B: y1, y2, , y_m; (m is not equal to n)
The two groups are independent but observations within each group are
not independent,
i.e., x1, x2, ..., x_n are not independent; but x's are independent from
Hello,
I have what I suspect might be an easy problem but I am new to R and
stumped. I have a data set that looks something like this
b-c(2,3,4,5,6,7,8,9)
x-c(2,3,4,5,6,7,8,9)
y-c(9,8,7,6,5,4,3,2)
z-c(9,8,7,6,1,2,3,4)
data-cbind(x,y,z)
row.names(data)-c('a','b','c','d','e','f','g','h')
which

I would like to randomize data within columns.
I think the following line does what you want (minus preserving the row
labels):
apply(data, 2, sample)
Maybe someone smarter than me knows how to preserve the row names. I
would
